IMPROVE!) MACHINE FOR RE-PRESSING BRICKS The Schedule referred to inthese Lettera Patent and making part of the same,

To all whom it may concern Be it known that I, HENRY MAURER, of NewYork, in the county and State ot' New York, have invented new and usefulImprovements in Machines t'or lie-Pressing Bricks; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings, making part of thisspecification, and to the letters oi' reference marked thereon.

Figure I represents a top view or plan of my iinproved machine;

Figure l'I is a longitudinal section of the same; and

Figure 1H is a cross-section atlinc V VI in Fig: I1.

Similar letters represent similar parts.

The nature of my invention consists inthe arrangement of suitableescape-openings in the mould-box, wherein the formed bricks areris-pressed, for thepurpose of receiving any ot' the surplus materialwhich may be in the original or first-made blick, insuring thereby theregularity of the bricks when the same are re-pressed.

In the accompanying drawings- A represents the framing oi' the machine,the front and back of nhich are strengthened and securely fastenedtogether, by bolts a a, situated in the line with the centre of themould-box B.

This mould-box is arranged near the middle, in the flaming A, and intowhich a piston or platen, C, is fitted, supported and guided on thebolts a, a.

Another' pistou or platen, D, likewise guided on the bolts a, a, isarranged to enter the front ofthe mouldbox B.

This platen D is connected to a toggle-joint, E, operated by a cam, F,placed on the revolving slndt S, whereby this platen D is moved into themould-box B, to act upon the brick to be rie-pressed.

A spring, b, acting upon one ot' the levers forming the toggle-joint E,will causo said joint to be moved or pressed downwards, for the purposeol'drawing the platen D ont oi1 the mould-box l, after the brick hasreceived the desired amount ot` pressure, and when the toggle-joint isrelieved t'roln the action of the cam F.

As soon as the platen l) is withdrawn out oi' the mould-box l5, nprojection, n, on a cam, l, on the shaft S, comes in contact with n,projection, 2, on the level' H, which latter is connected, through thelever J, with the pinten U, in suoli a manner as to move said platen Cfurther into the mould-box ll, and thus push the pressed brick out otAsaid mould-box upon :L block or table, l, situated iu the l'ront otsziidmouldbox.

\Vhcn the pressed brick has been moved upon the block li, the cani L onthe shat't S operates the lover M, connected with the guide-rod P of theblock K,

and moves thereby this block K, with the pressed brick, upward in a linewith the top face ofthe frame A.

On the top of the frame A, above the block K, a slide, N, is arranged,with au open slot on its forward end, and an opening, d, capable ofreceiving and passing through ita common brick.

This slide is connected, through the lever 0, with a lever, Q, whichlatter is provided with a projection, m, working against the face of aneccentric disk, R, (see Fig. 1,) fast on the end of the shaft S, andthrough which motion is communicated to said slide N, as soon as theblock K has been moved on a line with the top of the frame, wherebythe-pressed brick is removed from the top of the block K, and theunpresscd brick, previously placed into the opening d, in the slide N,is left upon the top of said block.

The block K is then moved downward, so as to bring` the impressed brickopposite the opening in the mould-box B, when the toggle-joint E isacted upon bythe cam F, causing thereby the platen 1) to be moved towardand into the mould-box B, whereby the unpressed brick is moved from thetop of the block K, pushed into the mould-box, and then receives therethe desired amount ot' pressure.

Through the sides of the mould-box B openings :n are made, (only two areshown in the drawings, through the top,) into which pistons n arefitted, acted upon by powerful springs e.

\Vhile the bricks are re-pressed in the mouldbox B, any excess ofmaterial which may be in the brick, as tirst moulded, will escape intothese openings, by pushing back the pistons n in the same, and preventthereby any dissi-rangement or breakage of' the machinery, at the sametime insuring the regularity of the bricks.

When the platen O is operated so as to push the pressed brick ont ot'the mould, the springs o acting upon thc pistons n in the holes x, willforce this material ont of the holes again, after the platen C haspassed the holes, and the material thus thrown into the mould-box willbe cleared out of the same by the backward motion of the platen C.

I (ind that in practice, two holes through the top ol' the mould-box, asrepresented in the drawings, are sufiicientin most cases; but anynumber, similarly arranged, may be made in the sides and bottom, as maybe found necessary and desired.

The block or table K is made hollow, so as to forni a cavity, w, toreceive oil or any other lubricatingsubst-ance.

This cavity is connected by suitable holes, with pieces of cloth,sponge, or its equivalent 3 3, arranged on each side ot the block E,which comes in contact with the faces ot' the platen D and C during theupward and downward motion of said block K, and oil or grease therebythese faces, after euch operation of conjunction with the solid plungers(i D, in the inunre-pressing a brick. ner und for the purpose herein setiol-th.

Into this cavity u' a. suitable piston nmy he tted, 2.
